Air Conditioning as a Heater in Winter

Why Use Air Conditioning for Heating?
- Dual Function – Heat in winter, cool in summer with one compact system.
- Energy Efficient – Up to 4 times more efficient than electric heaters.
- Lower Bills – Reduce energy costs compared to portable heaters or older systems.
- All-Electric – No need for gas — just plug into your electricity supply.
- Fast & Reliable – Heats rooms quickly, unlike radiators that take time to warm up.
- Clean & Healthy Air – Built-in filters improve air quality while heating your space.
How It Works?
Air conditioning units use reverse-cycle technology. In summer, they remove warm air from your home. In winter, the cycle is reversed — the system extracts heat energy from the outdoor air and transfers it inside, keeping your space cosy even in cold weather.
This makes air conditioning one of the most eco-friendly and cost-effective heating solutions available in London today.

Yes — modern heat pump systems work efficiently even in outdoor temperatures as low as -10°C.
Is it expensive to run?
Not at all. Heat pump AC systems are far cheaper to run than electric radiators and use less energy.
